This is...all wrong. He wasn't talking about the first Super Saiyan, he was talking about the most recent Super Saiyan to exist. He didn't get Golden Ape in the humanoid form, it's just that he required Great Ape's durability enhancement so that the Super Saiyan transformation didn't burn him out. He didn't shatter the planet he was on and suffocate, it was that the Super Saiyan transformation was so powerful that it consumed him despite the durability enhancement of Great Ape. The Super Saiyan he was talking about came a thousand years before he did and the Saiyans only gained access to planets beyond Planet Plant a few decades prior, during the reign of King Vegeta. If the previous Super Saiyan shattered the planet he was on, the Saiyans would've gone extinct a millennium before Prince Vegeta was born.
